Hey guys, I just bought a 2013 335i with the m-sport package. I did some research on the car before I bought it and so far I love it! I've never owned a BMW until now so im looking to do some aftermarket performance upgrades.

Its got around 87k miles so im looking for recommendations for maintenance before I start making changes and what performance parts anyone who has an F30 recommends.

I'd go through all the fluids personally as that's what I do whenever I get a vehicle with no known history, or prior to modifications.

At the minimum:

Engine oil
Transmission fluid
Differential
Brake fluid
Engine air filter

For performance the absolute best bang for your buck is a JB4 tuner. Most people just get that and are satisfied and is the most hp/dollar you will get.

With the tuner you can then start looking at things like coil packs/ spark plugs, air intake& exhaust modification. That includes things such as downpipes, mufflers, I/C & piping.

I'd like to clarify all of this is my opinion and everyone will have mixed reviews.
